Organizational governance is the combination of processes and structures that help the organization achieve its objectives2. Ethics activities are part of organizational governance, as they reflect the organization's values, culture, and ethical standards3. Internal audit can assess the ethics activities by evaluating the design and effectiveness of the ethics program, policies, and procedures, and providing assurance and advice on how to improve them4.
